Best-selling author Mark Shaw returns to The Commonwealth Club to discuss his latest book, Collateral Damage, in his ongoing investigative research into the connections between the mysterious deaths of motion picture screen siren Marilyn Monroe, President John F. Kennedy, and "What’s My Line?" TV star and crack investigative reporter Dorothy Kilgallen.

Shaw argues that if Robert Kennedy had been prosecuted for what Shaw calls his complicity in the death of Marilyn Monroe in 1962, his campaign against Mafia leaders as attorney general would have been sidetracked, and so there would have been no reason for Bobby’s Mafia enemies to assassinate his brother JFK in 1963. There would also have been no reason for them to kill media icon Dorothy Kilgallen, since it was her explosive investigation into JFK’s death that led to the famous reporter’s death in 1965.
